I’m currently reading about the TPM and remote attestation. Here’s my current understanding of what is happening.
To attest a PCR value to a remote party, the TPM signs the value with an attestation key (AK). This AK is not linkable to th… Continue reading Is anonymous remote attestation viable?
I need to create an attestation key (AK) and use it to sign arbitrary data in TPM 2.0. The TCG Guidance documents, suggest that some TPMs may come pre-provisioned with an AK that is part of the endorsement hierarchy. I am wondering if ther… Continue reading How can I create restricted signing key or attestation key and certify it in TPM 2.0?
HELP ME! My pc has been hacked I have sooooo many files that I have not added I am having issues with user access and owner rights. Mind you this is after I had done a clean install from flash drive wipeing the hard drive rem… Continue reading Help best free or reasonable security options after Remote-ATTESTATION infected files
It is known that is possible to define an NV Extend Index which has a behaviour similar to a PCR (Platform Configuration Register) and it is possible to modify it using TPM2_NV_Extend() operation.
Now if I want to use this s… Continue reading Perform quote operation over NV-memory in TPM
I’m a little bit unclear reading this from an article
A TPM can also be used to store
platform measurements that help ensure that the platform remains trustworthy.
Authentication (ensuring that the platform can prove… Continue reading Are Authentication and Attestation two different process?
I’m a little unclear on this (marked strong):
“The public key authentication functions provide for on-chip key pair generation using a hardware
random number generator, along with public key signature, verification, encrypti… Continue reading TPM with the three main groups of functions
I am currently reading up on Intel’s SGX, especially the remote attestation part. I am having a questions regarding this topic.
Let us consider the following protocol:
Enclave A and B do remote attestation. Each of them gen… Continue reading Intel SGX – Remote attestation
My computer was placed into a lan network without my consent. Since that happened I have absolutely NO control over any aspect of the system. I have tried everything to regain control with no results. I do know I am in stack … Continue reading Remote Access Networking
I have a question about Remote Attestation and measured boot with a TPM-Module.
The illustration shows my project schematically. A TPM module will be used to measure the boot process and validate user applications. The ker… Continue reading Using the TPM module to measure boot process and remote attestation
In android there is a way of knowing if the public key from a key pair was generated inside TEE and is, therefore, hardware-backed (https://source.android.com/security/keystore/attestation). I cannot find a way to do that in … Continue reading iOS hardware-backed key attestation
